Definitions
- the present application relates to the field of telecommunication technology, in particular to a method of transmitting a beam failure recovery request and user equipment (UE).
- UE user equipment
- radio signals In a high-frequency band communication system, radio signals have a relatively short wavelength, and as a result, communication is susceptible to interruption due to the blockage of signals, the movement of UE or the like. When communication is interrupted, the system needs to recover communication through beam failure recovery.
- UE acquires a hypothetical physical downlink control channel (PDCCH) block error rate (BLER) by monitoring a downlink beam for a beam failure detection reference signal in a physical layer, determines that the downlink beam fails if the acquired hypothetical PDCCH BLER exceeds a preset threshold, and determines that a beam failure event occurs if the UE detects that all hypothetical PDCCH beams fail.
- PDCCH physical downlink control channel
- BLER block error rate
- the UE transmits a beam failure recovery request to a network side device on a contention-free physical random access channel (PRACH).
- PRACH contention-free physical random access channel
- a base station transmits a response signaling to the UE after receiving the beam failure recovery request transmitted by the UE. After receiving the response signaling transmitted by the base station, the UE performs beam failure recovery according to the response signaling transmitted by the base station.
- the UE further needs to transmit other uplink channel or signal while transmitting a beam failure recovery request by using a PRACH resource, due to limitations with respect to factors such as uplink transmit power and antenna structure of the UE, the beam failure recovery request based on the PRACH resource and the other uplink channel or signal cannot be transmitted simultaneously, resulting in that the beam failure recovery request cannot be transmitted properly.
- Embodiments of the present application provide a method of transmitting a beam failure recovery request and UE, to resolve the problem in the related art that a beam failure recovery request cannot be transmitted properly when the beam failure recovery request and other uplink channel or signal need to be transmitted simultaneously.
- the present application provides in some embodiments a method of transmitting a beam failure recovery request, applied to UE, including:
- the beam failure recovery request transmitting, in a case that it is determined that a first time period for transmitting a beam failure recovery request and at least one second time period for transmitting an uplink channel or signal overlap and the uplink channel or signal supposed to be transmitted within the at least one second time period does not carry any beam failure recovery request, the beam failure recovery request to a network side device within the first time period.
- the present application provides in some embodiments UE, including a processing unit and a transmission unit,
- processing unit is configured to: in a case that it is determined that a first time period for transmitting a beam failure recovery request and at least one second time period for transmitting an uplink channel or signal overlap and the uplink channel or signal supposed to be transmitted within the at least one second time period does not carry any beam failure recovery request, control the transmission unit to transmit the beam failure recovery request to a network side device within the first time period.
- the present application provides in some embodiments UE, including: a processor, a storage, and a computer program stored in the storage and configured to be executed by the processor, where the processor is configured to execute the computer program to implement the steps in the method of transmitting a beam failure recovery request according to the first aspect.
- the present application provides in some embodiments a computer-readable storage medium, storing therein a computer program, where the computer program is configured to be executed by a processor to implement the steps in the method of transmitting a beam failure recovery request according to the first aspect.
- the UE transmits the beam failure recovery request to a network side device within the first time period. That is, in the embodiments of the present application, a priority level of transmitting a beam failure recovery request is higher than a priority level of transmitting other uplink channel or signal. Therefore, in the embodiments of the present application, the normal transmission of a beam failure recovery request can be ensured when a time period for transmitting a beam failure recovery request conflicts with a time period for transmitting other uplink channel or signal, so that communication efficiency can be improved.

Alternatively, first, it may be determined whether the uplink channel or signal supposed to be transmitted within the at least one second time period includes any beam failure recovery request, and then it is determined whether the first time period for transmitting the beam failure recovery request and the second time period for transmitting the at least one uplink channel or signal overlap.

- the step S 23 includes: transmitting, by the UE, the beam failure recovery request to a network side device within the first time period.
- a priority level of transmitting the beam failure recovery request is higher than that of transmitting any other uplink channel or signal, so that when the first time period for transmitting the beam failure recovery request and the second time period for transmitting the uplink channel or signal overlap and the uplink channel or signal supposed to be transmitted within the at least one second time period does not carry any beam failure recovery request, the beam failure recovery request is preferentially transmitted.
